Given an integer n, the task is to print the numbers who consist only 0’s and 1’s and their sum is equal to the integer n.The numbers which contain only zeros and ones are 1, 10, 11 so we have to print all those numbers which can be added to ... Read More

Given with an array of integer elements, the task is to remove the duplicate values and print the distinct elements in sorted manner.Given below is an array that stores integer type values in the fashion 4, 6, 5, 3, 4, 5, 2, 8, 7 and 0 now, the result will ... Read More

We have to print the data of nodes of the linked list at the given index. Unlike array linked list generally don’t have index so we have to traverse the whole linked list and print the data when we reached a particular.Let’s say, list contains the nodes 29, 34, 43, ... Read More

We are given an positive integer n and make a spiral matrix of n x n, with only using O(1) extra space in clockwise directionSpiral matrix is a matrix that works like a spiral which will start from the origin of a circle and rotates in clockwise fashion. So the ... Read More

We have to print the k number of nodes of the linked list in reverse order. We have to apply the iterative approach to solve this problem.Iterative method is the one which generally uses loops that are executed till the condition holds value 1 or true.Let’s say, list contains the ... Read More
